Class Method Details

.c14n_build_ns_pointer(inclusive_namespaces) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Builds a NULL-terminated const char** from a Ruby array of strings, suitable for passing to leptris_c14n_canonicalize_ex's inclusive_ns_prefixes argument. Returns [pointer, anchor] where anchor is the underlying MemoryPointer that the caller must keep alive (e.g. via local variable) for the duration of the FFI call.
